1 PRACTICE EXAM (not all questions pertain to a specific mid-term). This is taken from an earlier final exam. 1. (4 pts) Permanganate ion oxidizes sulfide ion to elemental sulfur (which you should represent as a single S atom) and is reduced to MnO2 in basic solution. In the balanced equation for this reaction‚ which you should determine in the work area‚ how many water molecules and hydroxide ions are needed in the final balanced equation? Work area: # of H2O ____4______ # of OH-

Yuri Anthony D. Sucgang BMLS-IA Electrophoresis Machine Gel Electrophoresis Apparatus(Aragose Gel) Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. Gel electrophoresis is a laboratory procedure used to separate biological molecules with an electrical current. In this lesson‚ we’ll review how agarose gel electrophoresis works and introduce the equipment necessary to perform an electrophoresis experiment.

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment
